Definitions

  • the present invention relates to a container capable of providing heat insulation, and which is suitable for transporting perishable products such as fresh fish, live mussels, frozen or chilled foods, cut flowers or plants or hot "take-away” foods.
  • such a container should be robust, to protect the product, and resistant to impact damage, so that the container is not easily damaged during freight handling.
  • the container also should be of minimum bulk, lightweight, inexpensive, provide an acceptable level of heat insulation, be easy to store before and after use, and be easy to dispose of in a manner which will not cause undue environmental pollution.
  • a lidded box of expanded polystyrene is lightweight and provides acceptable heat insulation, but is bulky, easily damaged (especially by impact) and often is not completely waterproof.
  • polystyrene is not biodegradable, and burning polystyrene under normal conditions (i.e. other than with excess oxygen) tends to produce soot and unpleasant fume. If freons have been used in the production of the polystyrene, these freons are liberated when the polystyrene is burnt. Also, polystyrene is very susceptible to sol­vent damage.
  • a further object of the invention there­fore is the provision of a container which provides an acceptable replacement for a polystyrene container, with all the advantages, but none of the disadvantages, of polystyrene.
  • the present invention provides a closable con­tainer formed from a composite material having a thick­ness less than or equal to 4 mm, said material comprising: a layer of tough, impact-resistant support material to at least one face of which is laminated a layer of metallized flexible plastics film having on one surface thereof a layer of vacuum-deposited metal, said metal layer having a thickness in the range 90-360 Angstroms (preferably 100-200 Angstroms); said con­tainer being capable of providing heat insulation for its contents such that ice/water at 0°C held inside said closed container remains at 0°C for at least 20 hours, when the ambient temperature surrounding said closed container is 20°C.
  • the terms “tough” and “impact-­resistant” are used in comparison with a polystyrene container.
  • the containers of the present in­vention are neither tough nor impact resistant compared to (for example) steel, but they are very considerably tougher and more resistant to impact damage than polys­tyrene.
  • the support material may be rigid or flexible, depending upon the particular application of the con­tainer; preferably, the support material is card, most preferably, corrugated card.
  • the term "card” includes both solid and corrugated card
  • the plastics film may be any suitable film which is inert to the produce to be packed in the container e.g. polyester film or polypropylene. It is believed that a number of different metals may be deposited on plastics film using vacuum-deposition techniques, but to date the most commonly-used metal is aluminum. Ob­viously, any metal used must be non-toxic and com­patible with the film.
  • the preferred metallized plastics film is polyester film metallized with aluminium, in par­ticular, 48 gauge polyester film having an aluminium layer 100 Angstroms thick.
  • This film has low oxygen permeability and a low rate of water vapour transmis­ sion, compared to a range of other commercially-­available films, as shown by the test results quoted in the Association of Industrial Metallizers Coaters & Laminators Technical Reference Book (Issue I).
  • this film is capable of providing efficient waterproof­ing for the composite product.
  • the metallized plastics film may be laminated to one or both sides of the support material, and may be laminated with the metal layer adjacent the support material or with the plastics layer adjacent the sup­port material.
  • the former is specified, because then the foodstuffs con­tact only the inert plastics film:- many foodstuffs regulations prohibit direct contact between foodstuffs and aluminium.
  • the metal layer lies adjacent the support material, so that the plastics film protects the metal layer from abra­sion by the product, and also provides waterproof con­tainment for the product.
  • the finished composite material is folded, or cut and folded, using known box making techniques to make any desired style of container.
  • the layer of plastics film forms the inner surface of the container, at least for the body of the container.
  • the support material provides the physical shape and strength of the con­tainer, plus some thermal insulation, and the metall­ized plastics film provides waterproofing and further thermal insulation, because the metal layer provides a thermally-reflective surface.
  • the support material is a solid card, then the metallized plastics film may be laminated to it using known laminating equipment and techniques.
  • the preferred support material is corrugated card, be­cause corrugated card provides good heat insulation and is light and inexpensive.
  • corrugated card means card with a corrugated core sandwiched between, and glued to, two outer layers of smooth card or heavy paper.
  • Laminating generally is carried out in a graphic hot laminating machine (e.g. a Duophan Billhofer Laminator), but it is accepted in the industry (and by the manufacturers of such machines) that these machines do not operate satisfactorily when the feed card stock is corrugated card:- the core of the card tends to be crushed in the laminating process, and this ruins the final product.
  • a graphic hot laminating machine e.g. a Duophan Billhofer Laminator
  • the present invention provides: a graphic laminating machine comprising: a conveyor for support­ing card to be laminated, and for carrying said card between a heated driven nip roller and an idler pres­sure roller; said pressure roller being movable towards said nip roller by means of an hydraulic ram which is provided with a pneumatic cushion arranged such that said pressure roller is cushioned if the pressure ap­plied thereby exceeds a predetermined value; the lon­gitudinal axes of the nip and pressure rollers being parallel and substantially perpendicular to the lon­gitudinal axis of the direction of motion of the con­veyor; a bow roller comprising a stationary roller bowed along its length and mounted adjacent the nip roller such that the bow is upwardly convex, with the length of the roller parallel to the longitudinal axis of the nip roller; the length of the bow roller being equal to or greater than the width of film to be laminated to said card; and guide means
  • the present invention further provides a method of operating said machine, including: placing sheets of card to be laminated on said conveyor; providing a supply of metallized plastics film (as hereinbefore defined); guiding said film by said guide means through said adhesive-applying apparatus, then over said bow roller before said film reaches said nip roller, such that the curve of said bow roller stretches and ten­sions said film, and then onto the upper surface of said card and between the nip and pressure rollers; and adjusting said pneumatic cushioning such that the pres­sure applied by the pressure roller to the card plus film remains below said predetermined value, regardless of variations in thickness of the card.
  • the machine is basically a Billhofer Duophan 2400-Type AVK102 graphic hot laminating machine. Since the machine is of well-known design, only its essential features, and the modifica­tions occasioned by the present invention will be described.
  • the machine 2 includes a control panel 3, a con­veyor 4 which extends the full length of the machine, holders 5 for supporting a roll of material to be laminated onto the card stcck, and a series of rollers 6 for guiding said material through adhesive-applying equipment 7 and then through an oven 8, where the adhesive is partially dried.
  • said material travels down towards the conveyor 4 along a sloping path directly to a nip roller 14.
  • said material travels from the outlet of oven 8 and over a bow roller or banana roller 13, which is added to the modified machine.
  • the machine of the present invention operates as follows: a roll 10 of metallized plastics film 11 is mounted on the holders 5, and the free end led through the machine ready for start-up. In its path through the machine, the film 11 travels through the adhesive-­applying equipment 7 which comprises an adhesive trough, an applicator roller, and a doctor roller (not shown), all of which operate in known manner. Alterna­tively, other suitable known adhesive-applying equip­ment may be substituted.
  • the bow roller 13 is somewhat longer than the width of the film 11, and its length is perpendicular to the direction A of movement of the conveyor.
  • the bow roller 13 is bowed along its length, and is ar­ranged with the bow upwardly convex.
  • the film 11 passes over the roller 13
  • the film is both supported and slightly stretched.
  • the natural elas­ticity of the film ensures that it contracts back to its original width as it leaves the bow roller 13, but the said slight stretching ensures that the film is completely flat and at the correct tension as it passes over the nip roller 14.
  • Corrugated card stock is placed on the beginning of conveyor 4 by hand or automatically.
  • the card stock generally is in rectangular sheets, and adjacent sheets are overlapped at the ends, to provide a continuous surface to which the film can be laminated. Alterna­tively, adjacent sheets can be butted together, but this is more difficult to arrange, and the laminated end-product is less satisfactory.
  • the conveyor 4 is perforated, and suction is ap­plied below the conveyor to hold the card stock tightly down onto the conveyor.
  • the conveyor carries the card stock towards the nip roller 14 and the pressure roller 15.
  • the film 11 is guided down from the bow roller 13, around a guide roller 13a, and over the nip roller 14, so that the adhesive-coated surface of the film contacts the upper surface of the card stock.
  • the film and the card stock are then pressed together by the nip roller 14 and pressure roller 15.
  • the nip roller 14 is a heated, chrome-surfaced calendar roller, and is driven.
  • the pressure roller 15 is aligned with the nip roller such that the lon­gitudinal axes of the rollers lie in the same vertical plane.
  • the pressure roller 15 is a rubber-surfaced idler roller and can be moved towards or away from the nip roller by means of one or more hydraulic rams (not shown).
  • the pressure roller 15 applies a pressure up­wards towards the nip roller:- a typical pressure ap­plied by the pressure roller is 5000 kilopascals where standard E-flute corrugated card is being laminated.
  • the or each hydraulic ram includes a pneumatic cushion, which cushions the sudden increase in pressure when said overlap portion (or any other portion of increased thlckness) is reached, and prevent the pressure applied by the pres­sure roller from exceeding a predetermined value.
  • the final laminated product leaves the end of the machine and may be cut into portions as required.
  • the film is securely laminated to the card stock, so that the laminate board can be die-cut or scored if re­quired.
  • the adhesive applied to the film may be any suitable solvent-based or water-based laminating adhesive (e.g. 408-40 Morton Tycol).
  • the adhesive must have a good green-tack strength.
  • the thickness of the adhesive layer applied to the film depends upon the type of card stock to be used, and in particular upon the absorbency of its surface. Similarly, the tempera­ture of the nip roller depends upon the materials being used.
  • laminated corrugated card may be produced by modifying the equipment which produces the corrugated cardboard itself, to produce the laminated corrugated card in a single in-line process in which the metallized plastics film is laminated to one of the webs of heavy paper (for forming one face of the cor­rugated card), and this lamination is then combined with the central layer of corrugated cardboard and the other layer of heavy paper which forms the other face of the corrugated card, to form the laminated cor­rugated card. If any other layers are required (for example, a second metallized plastics layer or an outer layer of plasticised sheet) these also are incorporated in the process.
  • the metallized film laminated corrugated card of the present invention present no especial problems to boxmakers, and may be made into boxes using any of a range of known box-making techniques.
  • the preferred boxmaking technique is that known as a "wet-lock" box, in which the base is folded in such a way that it is waterproof.
  • a box of this type may have an integrally-formed lid or a separate lid.
  • Tests 1 and 2 were carried out by the New Zealand Government Depart­ment of Scientific & Industrial Research, and Test 3 by an independant consultant on food microbiology.
  • the containers of the present invention were made from card to at least one face of which was laminated 48-gauge metallized polyester film having an aluminium layer of approximately 100 Angstroms. The lamination was carried out on the above-described machine.
  • the trays were then placed inside the containers which were housed in a closely controlled environment room at 20.0°C ⁇ 0.5°C.
  • the boxes were positioned to achieve equivalent thermal ambient conditions, taking into account convective and radiant effect, and the tray temperatures monitored continuously.
  • the containers of the present invention provided heat insulation comparable to a polystyrene container having a wall-thickness of 27 mm i.e. 18 times thicker than the 1.5 mm thick laminated cor­rugated card container or 13.5 times thicker than the 2 mm thick laminated solid card container.
  • This test also demonstrated the superior insulating properties of corrugated card, as compared to solid card; corrugated card 1.5 mm thick provided equivalent insulation to solid card 2.0 mm thick.
  • the object of this text was to establish whether a two-piece "wet-lock" box made in accordance with the present invention was capable of providing an hermetic seal, in case the heat insulating properties of the box could be attributed wholly or partly to the presence of an hermetic seal i.e. to find out whether the heat in­sulating properties of the box were due to the material of which the box was made, or to its design and con­struction.
  • the container was subjected to an internal air pressure to determine whether the container remained air-tight under usual air freight conditions.
  • the internal air pressure was set at 15 kPa, as determined by the usual airline practice of pressuriza­tion of freight holds to the equivalent height of 1500 metres.
  • a mercury manometer was used to measure the ap­plied pressure and also to determine whether the con­tainer held the pressure when valved off from the con­trolled and regulated air supply.
  • the plastic internal liner was also tested to 15 kPa after sealing the top opening with masking tape.
  • the container was found to be not capable of remaining air-tight under normal airfreight conditions. Air pressure was not maintained within the container for more than one half second after valving off of the air supply.
  • the plastic liner, as prepared, was capable of providing an hermetic seal.
  • the container itself is not capable of providing an hermetic seal. Since the containers tested in the Thermal Performance Test were not provided with an inner liner, it must be concluded that the material of the box, rather than any particular design of box, was responsible for the heat insulation properties.
  • This test was designed to study the rate and pat­tern of spoilage of fish in containers in accordance with the present invention, and to compare this with the rate and pattern of spoilage of fish in polystyrene containers.
  • Fish was selected for these tests because fresh wet fish is a very difficult product to store and transport:- fish tends to have a high bacterial count even when completely fresh, and since bacteria (given suitable conditions) will double in number as often as every 20 minutes, the spoilage of fish, which provides a particularly favourable environment for bacterial growth, can be very rapid. In practical situations, fresh fish needs to be kept in good condition for 12-16 hours.
  • the test comprised two separate trials, in each of which chilled fresh fish fillets in 10 kg lots were packed in plastic bags (not sealed) and then into each of five boxes in accordance with the present invention and into five polystyrene fish boxes.
  • the boxes in accordance with the present invention were two-piece boxes of the "wet-lock" design with in­ternal dimensions 400 mm x 300 mm x 140 mm and an over­all thickness of card of 1.5 mm.
  • the metallized-film layer was on the interior of the base of the box and on the exterior of the lid.
  • the polystyrene fish boxes had internal dimensions (mm) of 552 mm x 337 mm x 118 mm, with a wall thickness of 27 mm, and were two-piece boxes of known type.
  • the containers of the present invention are capable of maintaining ice/water at ice-point (0°C) for approximately 26 hours, in an ambient temperature of 20°C, and of sufficiently insulating fresh fish so as to delay the onset of spoilage for 48 hours, at an am­bient temperature of 4°C.
  • the containers of the present invention would comfortably exceed the minimum conditions required for containers for perishables, even when used with fresh wet fish (which generally is considered to be one of the most difficult perishables to freight).
  • the composite material of the present invention can be made up using any standard box-making designs, it is easy to manufac­ture a container which can be folded flat before and after use, to minimize storage space. This gives the containers of the present invention a considerable ad­vantage over polystyrene containers, which of course cannot be folded down at all.
  • the very thin walls of the containers of the present invention greatly reduce the overall bulk of each container. Indeed, substituting containers of the present inven­tion (with wall thickness 1.5 mm) for equivalent polys­tyrene containers results in approximately 53% reduc­tion in total volume, for the same weight of produce in the containers. Obviously, this reduction in volume produces considerable savings in freight costs.
  • a further advantage of the containers of the present invention is that product may be blast-frozen in the containers - this is not possible with polys­tyrene containers.
  • the containers of the present invention may be burnt (preferably using forced draft incineration) without producing significant quantities of noxious gases, and, in the long term, are bio-degradable providing the polyester film is exposed to sunlight.
  • burning polystyrene produces heavy soot and unpleasant fumes, and may liberate freons (for this reason, it is banned in many countries) and polystyrene is not bio-degradable, even in the long term.
  • the containers of the present invention in general cost about 2 3 or less of the cost of an equivalent polystyrene container, and are much less susceptible to damage in freight handling, since the card is in­herently much tougher and more resistant to impact damage than polystyrene.
